Precision and Practicality

Ascent i expresses MartinLogan's signature language of form and function, maintaining controlled dispersion with outstanding dynamic range, imaging, and detail—all from a rigidly braced, sculpted cabinet that is sleek and beautifully finished. The soundstage, openness, and accuracy exhibited by Ascent i's large, reference-quality electrostatic transducer, high-resolution woofer, and audiophile-grade crossover allow the Ascent i to excel as a stereo or home theater front-channel in any room.
